At 9:35 a.m. on July 22, a total solar eclipse will be staged over the densely populated Yangtze River basin in China. This will be the longest visible total solar eclipse in China since 1814, with the largest number of observable people and the most spectacular scenery.

At 8:30 a.m. 10:30 a.m., we will observe the most spectacular total solar eclipse once in 500 years in Quzhou, and gradually the time comes to the total solar eclipse, I immediately took out my sunglasses and faced the sun, only to see a round of fiery red sun in the black back, and then like a tengu eating the moon, there are cracks on the sun that are bitten by teeth, 1 minute has passed, I am watching the sun disappear little by little, when the moon blocks the sun all, the sky is dark and I can't find any traces of the sun. Gradually, I saw a star-like thing and a black sun, only to see that the sun was like eating a fairy's Yaochi fairy dew and began to slowly recircle again, the sky was bright again, and the stars were gone, the world is really wonderful!

But I don't know why a solar eclipse happens, and I only blame me for not learning enough, so my father, a jack of all trades, immediately told me about .........It turns out that a solar eclipse is a solar eclipse after the moon blocks the sun, and the sun does not shine on the earth, so it forms a solar eclipse. We saw it all five times, but there were a lot of clouds, and the sun was in the clouds a lot of the time.

Principle of Solar Eclipse A total solar eclipse occurs because the Sun is close to a point where the Moon's orbit meets that of the Earth, and at the same time the Moon is at the closest point to that point. An annular solar eclipse occurs because the Sun is close to an intersection of the Moon's orbit and the Earth's orbit, and the Moon is at the farthest point from that point. Since the beginning of the food loss, it is the partial food stage.

As the moon continues to move eastward, the part of the sun's circle that is obscured by the moon gradually increases, and the intensity and heat of sunlight decrease significantly. When the eastern edge of the lunar surface is intangent to the eastern edge of the solar surface, it is called an eclipse. At this time, the entire circle of the sun is obscured, so the eclipse is the moment when the total solar eclipse begins.

The reason why a total solar eclipse occurs is because there is a magical symmetry. The Sun is 400 times the diameter of the Moon, and it is exactly 400 times the distance from the Earth. As a result, when the Moon is completely between the Earth and the Sun, the Sun's surface is completely obscured for those who are completely in the Moon's shadow.

The sun turned black, leaving only a golden halo, and the sky turned indigo. Birds may lose their orientation or fly back to their nests, while bats and other nocturnal animals may come out sleepy.

It's really a world full of wonders!

That's going to take so many words, and a few words will do it.

I'm sorry, I haven't seen it, so I can't talk nonsense. ”

I saw a total solar eclipse.

July 22, 2015, this is destined to be an unusual day.

On this day, a great drama that has been waiting for 500 years was staged - a total solar eclipse.

A total solar eclipse is when the moon rotates around the earth to the middle of the sun and the earth, the sun, the moon, and the earth line up in a straight line, the moon blocks the sunlight that reaches the earth, and the black shadow behind the moon falls on the earth, and the sun is close to the intersection of the moon's orbit and the earth's orbit, and the moon is at the nearest point from this point, which will produce a total solar eclipse. This phenomenon is rare and spectacular. We have been waiting for 500 years for this total solar eclipse in Hefei!

So, in my lifetime, I'm glad to see a total solar eclipse.

In the morning, I was so excited that I got up at 5 o'clock. When I looked out the window, I was secretly taken aback - the sky was not as usual, but gloomy and cloudy. "Can you see a total solar eclipse in this weather? "I'm worried," I hope the weather will get better soon. ”

At half past seven, I went out with total solar eclipse glasses.

There were a lot of people on the road - there would not be so many people in the morning, I guess they all came out to see the total solar eclipse.

At 10:10 a.m., I finally squeezed onto the Sanxiaokou overpass. Look at the people around me, the equipment is much more complete than mine, they are all special astronomical telescopes, like cannon barrels, pointing straight to the sky.

Firmament? By the way, I almost forgot, the sky at this time was still so overcast, and the dark clouds were tightly clasped in the sky over Hefei like a steel helmet, and there was no gap at all, and everyone present was worried.

At 8:18, this moment when it should have been the "first loss", all we saw was a blank expanse. Although I was depressed, I still looked at the sky with the mentality that the dark clouds might soon disperse.

Time passed minute by minute, but the sun never appeared in front of our eyes.

At half past nine, it was completely dark. At this time, it should be very fast, but unfortunately we can't change the demeanor of the sun with a face. Everyone present sighed in disappointment.

Yes, after waiting for 500 years of drama, it was so easy to miss it, no matter who it is, it will be regretted. After a while, the sky gradually brightened again, the crowd gradually dispersed, and the whole city returned to order. The next total solar eclipse in Hefei will be in 2039, where will I be?

The astronomical spectacle that has been long-awaited for so long may never be seen again in this lifetime.

Ironically, in the afternoon, the sky cleared. God played a vicious joke on us. Looking at the clear sky, I really wanted to say, "Sun, can you change your face for us again?" ”

The miraculous total solar eclipse quietly lifted her veil with cheers from all corners, she is so beautiful, and her appearance has written a new chapter in the land of China for 5,000 years!

I learned about the process of a total solar eclipse from the book, that is, the process of a total solar eclipse can include the following five periods: the first loss, the eclipse, the eclipse, the light, and the round.

I feel very fortunate to be able to see this once-in-a-century fantastic total solar eclipse, but perhaps because the weather is not beautiful, this morning's weather is like a masked girl, surrounded by clouds. I kept praying, hoping that the clouds could disperse and the long-awaited sun appeared, I silently counted the time, and suddenly the sky was clear, maybe the sun was moved by me, look at what it was, ah, it was a total solar eclipse, he came like a beautiful fairy, it was more than 9 o'clock, the sun was gradually blocked by the moon, like a red burning apple was slowly bitten off. There is a sense of mystery about me, who has never seen a total solar eclipse.

When the sun is about to be completely blocked by the moon, the sky turns dark, and I think it is a beautiful and spectacular watercolor that nature has given us human beings. And at the eastern edge of the sun, there will suddenly appear an arc of diamond-like light, like the striking sparkle on a diamond ring, which is the diamond ring, and at the same time instantly form a string of glowing bright spots, like a string of brilliant pearls hanging high in the dark sky, this phenomenon is called pearl eclipse. Slowly, the sun returned to its original state.

Although the total solar eclipse is only once for us, but for the whole China, and even the whole world, it is a rare wonderful spectacle, I believe, the spectacle of the total solar eclipse once again proves that the universe is so big, there are no wonders, maybe the total solar eclipse is just a small beginning, and more unexpected wonderful landscapes will appear again in the universe!
